11. D(-2, 3), E(5, 5), F(-4, 10)
Find the measures of the sides of DEF,then classify it by its sides
Answers
Answer:
Step-by-step explanation:
Given the coordinates D(-2, 3), E(5, 5), F(-4, 10), to find the measure of the sides, we will use the formula for calculating the distance between 2 points as shown:
D = √(y2-y1)²+(x2-x1)²
For DE;
D(-2, 3), E(5, 5),
DE = √(5-3)²+(5-(-2))²
DE = √2)²+7²
DE = √4+49
DE = √53
For DF;
D(-2, 3), F(-4, 10)
DF = √(10-3)²+(-4-(-2))²
DF = √7²+(-2)²
DF = √49+4
DF = √53
For EF;
E(5, 5) F(-4, 10)
EF = √(10-5)²+(-4-5)²
EF = √5²+(-9)²
EF = √25+81
EF = √106
Since two he sides DE and DF are equal, this shows that the triangle is an isosceles triangle. An isosceles triangle is a triangle that has two of its sides and angle equal
the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answers
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

The camp athletic director wants to arrange kickball games for high school students and middle school students. Because of the ages of the campers, the high school kickball field is larger than the middle school field. The length of the square base path of the high school field is represented by the expression 2x−3 and the length of the middle school base path is represented by the expression x−8.
What is the area of the middle school field if its side measures x−8 feet?
What is the area of the high school field if its side measures 2x−3 feet?
Answers
Answer:
Step-by-step explanation:
The area of the high school field’s base path is (4x^2 -12x + 9) ft^2
The area of the middle school field’s base path is ( x^2 -16x + 64) ft^2
The difference in size between the two is
(3x^2 +4x - 55) ft^2
Step-by-step explanation:
Firstly, we are to calculate the area of the high school field’s base path
Mathematically, the area of a square is L^2
where L is the length of the side of the square. The area of the high school field base path is thus;
(2x-3) * (2x-3) = 2x(2x-3) -3(2x-3) = 4x^2 -6x -6x + 9 = (4x^2 -12x + 9) ft^2
The area of the middle school field’s base path can be calculated in a similar fashion
That would be (x-8) * (x-8) = x(x-8)-8(x-8) = x^2 -8x -8x + 64 =( x^2 -16x + 64) ft^2
The difference in size between this two will be;
(4x^2 -12x + 9) - ( x^2 -16x + 64) = 4x^2-x^2-12x+16x+9-64 = (3x^2 +4x - 55) ft^2

Regent Stadium charges $20 for a seat in the bleachers, $30 for an end zone seat, and $40 for the excellent seats near the 50-yard line. When the stadium is full, 500 tickets were sold for a total of $14,000. The number of bleacher seats is the same as the number of end zone and 50-yard line seats combined.
Answers
Answer:
The number of bleachers seat sold = 200
The number of end zone seats sold =200
The number of excellent seats sold =100
Step-by-step explanation:
Let there are bleachers seats =x
The number of zone seats =y
The number of excellent seats =z
So, we can set up equations for given sentences as
x+y+z= 500
20 x+30 y+40 z=14000
x=y
Substitute x as y into first two equations
y+y+z=500
20 y+30 y+40 z=14000
Simplify each
2 y+z=500
50 y+40 z= 14000
Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.
-80 y-40 z=-20000
Add this with 50 y +40 z=14000, which gives
-30 y=-6000
Divide both sides by -30
y=200
Now, plug in y as 200 into any of the equations to find z.
2(200)+z=500
400+z =500
Subtract both sides 400.
z=100
Now, we know x=y
So, x=200

if AB || CD, then find value of angle COS, if angle BPO = 120 + - and angle COS = x
Answers
====================================================
Explanation:
Angle BPO is congruent to angle POC because they are alternate interior angles and because AB is parallel to CD. So angle POC is 120+x degrees
This adds with angle COS to get 180
(angle POC) + (angle COS) = 180
(120+x) + (x) = 180
2x+120 = 180
2x = 180-120
2x = 60
x = 60/2
x = 30
angle COS = x = 30
angle POC = 120+x = 120+30 = 150
angle BPO = angle POC = 150
